[Tigers] Holley Rebuild - float bowls

[jay.laifman at gmail.com]

I'm worried that he never knew the bowls were way off and adjusted jets to compensate. It wouldn't be like him. But we'll see what happens when I reset them. The problem is that one is so off that there is no way the screw adjuster will be enough.  I'm going to have to bend it before reassembly. But thinking about how off it is, I'm also going to make sure it doesn't have any holes in it. 

Also, I'm used to Webers where the jets are easy to swap (and float level is critical).  I'm thinking the Holley is not so easy and he would have had to see the floats anyway to change the jets. 

The ox sensor.  I haven't paid too much attention to that other than to note it is frequently in the red. It has a row of lights going from green to yellow to red. Can someone tell me under what driving conditions should it be in the color bands?  Like idle, cruising, slowly accelerating and on it?  And is it likely to be accurate or could it be wrong because of a gazillion things?

Also,
The "rebuild" level is probably a low level just to get you going.  The instructions are
to always set the level wet after installation.
Float level has a minor(?) influence on mixture.  Your dad may have tweaked it based
on his ox sensor readings?

If your needle and  seat size is marginal (or if the fuel pump/fuel line flow capacity is not that  good) then having the floats low can cause starvation on sustained  full-throttle due to insufficient fuel volume in the carb. I'm not familiar  with the float setting procedure on the Holley carbs, but I'm sure there are  specific tweaks that can be done, depending on the float bowl style, to  alleviate the common driving concerns.    On many Weber carbs, you had to be a bit careful because the float high limit  was set by flipping the assembly upside down, and this would sometimes lead  people to adjusting the things in the wrong direction.
